Her message came after the group released a statement on this morning revealing the 19-year-old failed to inform her bandmates of her decision – and left it to her representatives to break the news.

Their announcement came just hours after the five of them took to the stage at iHeartRadio’s Jingle Ball in Florida.

The statement said: “After 4 and a half years of being together, we have been informed via her representatives that Camila has decided to leave Fifth Harmony. We wish her well.

Fifth Harmony have hinted at their secret feud after unfollowing Camila Cabello just hours after she quit the group

“You Harmonizers have been there with us since the beginning, you’ve supported us, you’ve rejoiced and cried with us, you’ve grown with us, and with your love and support, we will continue on.

“That being said, we are excited to announce that we will be moving forward with the four of us – Ally Brooke, Normani Kordei, Dinah Jane and Lauren Jauregui for our fans.”

In this evening's Twitter post Camila wrote: "When I turned 15, I had the blessing of being put into a group with four very talented girls, we were 5 strangers that weren’t even aware of each other’s existence that were given a shot at one dream together.

"It’s been almost 5 years and the most important chapter of my life this far. I am so proud of everything we’ve achieved together as a group and will always be proud of being a part of it.

"I was shocked to read the statement the fifth harmony account posted without my knowing. The girls were aware of my feelings through the long, much needed conversations about the future that we had during tour.

Camila said she will be persuing a solo career

"Saying that they were just informed through my representatives that I was ‘leaving the group’ is simply not true. Just like the other girls said in their statement about their plans, I had also planned to continue with my solo endeavors in the new year but I did not intend to end things with fifth harmony this way.

"As sad as it is to see this chapter ending this way, I will continue to root them all on as individuals and as a group, I wish nothing but the best for them, all the success in the world and true happiness.

Just as I said to them during those conversations, and just like I try to encourage you guys, I want to lead by example when I say to each of you guys to be courageous in the pursuit of what makes your heart pound and what makes you come alive with purpose, our happiness is our own responsibility, we only have one life and we never know how much time we really have, we don’t carry money, trophies, social media followers, fame, or success with us… we carry the memories that made us feel alive and the moments that made us fall in love with life.

"New chapters are scary, but conforming to what’s safe and looking back with regret is even scarier.

"Next year I will be working on my own music and giving you a big chunk of my heart. To our amazing fans, I will always be so thankful for the opportunities being in this group has given to me.

"I am even more thankful for the times that we’ve gone to get frozen yoghurt together and talk about music, for the times we’ve locked eyes during a lyric, for the hugs that put pieces back together in both of us, for more love than I can put into words, and for showing me the way to myself.

"You took 5 ordinary girls and made their dreams come true – and together, us and you guys, we’ve

written an amazing story – of girls from all different cultures, backgrounds, colours, shapes, languages, music tastes, all going for one dream – a dream I will never forget, the memories we’ve made together will last a lifetime, now I gotta walk the walk… I have always encouraged you to be fearless, to live your life in the name of love and do what makes you happy… as scary as it is to take the leap, I am excited and full of joy because I know that no matter what happens, I am following my heart. I hope to see you on my journey. Love only, camila."

The 20-year-old had “marijuana in her hand luggage” as she was preparing to travel from America to Brazil, according to a report from TMZ.

A police insider told the website: “Lauren was stopped at a TSA checkpoint and forced to submit to a secondary search, when a TSA staffer found what appeared to be a bag of marijuana in her carry-on luggage.

“Cops were flagged down in the terminal and they promptly arrested the singer.”

A spokesman for the airport confirmed Jauregui had been charged with possession and released on summons.

Lauren was flying out of Dulles airport in Virginia and heading to Brazil, where the band were performing at the VEVO FunPopFun Festival.

She was unable to join the group for the gig in Sao Paulo, but the show went on without her.

The band performed at the festival as a four-piece, but the pop star’s attorney has confirmed the incident at the airport “will not interfere with any future scheduled performances or activities.”
